Patent number: 10890693Abstract: A tunable acoustic gradient (TAG) lens includes an acoustic wave generating element and a refractive fluid in a casing cavity surrounded by a lens casing. The lens casing includes case ends which each include a window configuration, a case end rim portion and an enhanced axial compliance portion. The window configuration includes a window and a window mounting portion having an overall window mount dimension along the axial direction. The enhanced axial compliance portion is coupled between the window mounting portion and the case end rim portion and includes a reduced thickness region characterized by a material thickness that is at most 75% of the associated window mount dimension. The axial compliance portion is configured to enhance the axial deflection of the window mounting portion compared to the case end rim portion, when a periodic drive signal is applied to the acoustic wave generating element.Type: GrantFiled: December 20, 2018Date of Patent: January 12, 2021Assignee: Mitutoyo CorporationInventors: William Todd Watson, Isaiah Freerksen

Patent number: 10520650Abstract: A tunable acoustic gradient (TAG) lens is provided including a lens casing, a refractive fluid, a controllable acoustic wave generating element (e.g., a piezoelectric vibrator) and an external reservoir configuration. An operational volume of the refractive fluid is contained in a casing cavity of the lens casing. The external reservoir configuration includes a deformable external fluid reservoir that contains a reserve volume of the refractive fluid and that is connected to the casing cavity by a flow channel. The flow channel enables the refractive fluid to flow back and forth between the casing cavity and the deformable external fluid reservoir in accordance with expansion and contraction of the refractive fluid (e.g., due to changes in temperature). The lens casing, deformable external fluid reservoir and flow channel are configured as a sealed system, with no intentional gas volume included in the sealed system.Type: GrantFiled: June 5, 2018Date of Patent: December 31, 2019Assignee: Mitutoyo CorporationInventors: Isaiah Freerksen, Maxwell James Perkins
